Product Description:

The DMA 15A 1301-D is a servo drive module from Bosch Rexroth Indramat in the DMA Servo Drive Modules series. Installed in multi-axis control racks, it converts DC link energy into regulated three-phase power for synchronous and asynchronous motors in assembly lines, packaging stations, and material handlers. Acting as the power link between the motion controller and motor windings, the unit supports closed-loop speed and position regulation while its compact format fits dense cabinet layouts. This arrangement allows the rack to concentrate several coordinated axes in a limited amount of enclosure space.

Heat is removed by backplane air cooling, which channels airflow along the rear of the card into the common rack plenum. Motor position is resolved through a resolver, which supplies an analog angular signal that remains accurate over wide temperature swings. Data exchange with supervisory controllers uses the SERCOS interface, giving deterministic fiber-optic communication and standardized telegram formatting for synchronized motion tasks. A width of 50 mm lets multiple axes mount side by side in the rack, conserving panel space. Its electrical behavior follows the profile of the Servodyn-D series, which helps keep control response aligned with related drive modules in the same platform.

As part of the rack, the drive is a 3-phase module for synchronous and asynchronous motors, delivering symmetrical line-to-line voltages suited to permanent-magnet and induction designs. It is supplied as the standard variant, and its memory and terminal assignments follow the baseline feature set for this module type. The drive requires only power, feedback, and fieldbus connections for normal installation, which keeps wiring direct and easy to follow inside the cabinet. It is part of the DMA Servo Drive Modules family, so it shares mounting hardware and DC-bus connectors with companion axes in the same rack.
